Watch David Letterman’s Heartfelt Tribute to Robin Williams

Robin Williamstributes continue to pour in and last night on “The Late Show,”David Letterman gave his old friend a heartfelt sendoff. “I knew Robin Williams for 38 years,” he said. “I met him at [comedy club] the Comedy Store. He and I were kids…in those days, we were working for free drinks; some were working for more free drinks, than others.”

Letterman explained how he and all the other comedians were immediately intimidated by his comedic prowess, and how relieved they were when Williams landed roles on “Happy Days” and “Mork & Mindy.”

“It was nothing we had ever imagined before,” he said of Williams’ early stand-up. “We’re like morning dew, he comes in like a hurricane.” Letterman was obviously shaken by Williams’ passing – at the end of his remembrance, they put together a short montage of some of Williams’ best appearances on the “Late Show” and a rare clip of when the talk show host appeared on “Mork.”
